Description

A kind of counterflow-preventing drop bottle
Technical field
The utility model relates to plastic bottle bodies, and in particular to a kind of counterflow-preventing drop bottle.
Background technique
Usual eye drop bottle is contained using plastics, and bottle body includes body and drip nozzle two parts, and drip nozzle presents end cone Shape, hole portion extend to the structure of base cavity, in use, ooze liquid medicine from drip nozzle by squeezing body, need Extruding movement is more accurately controlled, when extruding force being avoided to spend the shake of big or finger, liquid medicine is caused to drip excessive phenomenon;Separately For such eye drop bottle using during not covering, the aperture of drip nozzle communicates with the outside world internal liquid medicine, mentions to a certain extent The risk that high internal liquid medicine is contaminated.
Summary of the invention
The purpose of this utility model is to provide a kind of counterflow-preventing drop bottles, when squeezing body, can avoid because squeezing dynamics The shake of excessive or finger, causes liquid medicine to drip excessive phenomenon;And it is non-do not cover during, avoid liquid medicine and the external world in bottle direct It communicates.
To achieve the above object, the utility model is implemented using following technological means:
A kind of counterflow-preventing drop bottle, including the tapered drip nozzle in body, upper end, which is characterized in that the drip nozzle is from upper end Tapered portion extends to form outlet tube to base cavity, and outlet tube lower edge depth is no more than base bottom wall, and from outlet tube entrance Aperture 0.05-0.1mm, the anti-reverse flow tube of height 1-2mm are formed, anti-reverse flow tube exports to tapered portion and topmost extends to form taper Flared aperture, base outer wall and body outlet inside wall are provided with the snap-in structure of pairing, are provided with above pedestal and compress body outlet The follow block of upper limb.
Further, the outlet aperture of the taper flared aperture is 1-2mm.
Further, the depth of the taper flared aperture is 5-12mm.
Further, at the tapered portion top, the reinforcement thickened is formed between taper flared aperture and anti-reverse flow tube Wall.
Further, the reinforced wall is with a thickness of the one third of tapered portion height to 2/3rds.
Further, the snap-in structure be set to base outer wall two layers of annular rim and with body outlet in The annular recess of wall pairing setting.
As another effective embodiment, it is additionally provided with bottle cap, is provided with enclosuring structure on the inside of the bottle cap upper wall, Bottle cap covers tightly under state, the outlet of the enclosuring structure sealing taper flared aperture.
Further, the enclosuring structure is the cyclic annular flanging for compressing tapered portion outer edge, and compresses taper flaring The sealing salient point in hole.
The utility model at least has following usefulness:
1. by the way that anti-reverse flow tube is arranged, after squeezing body and being oozed to medical fluid, loosens after body restores body deformation, produce It is drawn back into the medical fluid in taper flared aperture and anti-reverse flow tube under raw suction function, can prevent medical fluid from dripping, and counterflow-preventing Pipe is in the lesser capillary column in aperture, under the action of liquid level tension, the phenomenon that preventing medical fluid from dripping naturally;
2. after use in placement process, anti-reverse flow tube is detained a small amount of medical fluid and counterflow-preventing because capillary column acts on In pipe, the drawbacks of medical fluid is directly communicated by taper flared aperture with the external world in bottle is avoided, reduces medical fluid by outside contamination Probability.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model;
Fig. 2 is the schematic diagram of the utility model counterflow-preventing head.
Specific embodiment
In order to be more easily understood the purpose of this utility model, technical solution and advantage, with reference to embodiments, to this Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain that this is practical new Type is not used to limit the utility model.
Embodiment
As shown in Figs. 1-2, a kind of counterflow-preventing drop bottle, including the tapered drip nozzle 3 in body 1, upper end, drip nozzle 3 is from upper end Tapered portion 31 extends to form outlet tube to 32 cavity of pedestal, and outlet tube lower edge depth is no more than 32 bottom wall of pedestal, and from outlet tube Entrance, which rises, forms aperture 0.05-0.1mm, the anti-reverse flow tube 36 of height 1-2mm, and anti-reverse flow tube 36 is exported to tapered portion 31 topmost Taper flared aperture 33 is extended to form, the outlet aperture of taper flared aperture 33 is 1-2mm, depth 5-12mm, and in tapered portion 31 At top, the reinforced wall 34 thickened is formed between taper flared aperture 33 and anti-reverse flow tube 36;32 outer wall of pedestal and body 1 export Inner wall is provided with the snap-in structure of pairing, is provided with above pedestal 32 and compresses the follow block 37 that body 1 exports upper limb.
Preferably, setting reinforced wall 34 passes through the setting with a thickness of the one third of 31 height of tapered portion to 2/3rds 33 upper limb of taper flared aperture of tapered portion 31 also can be improved while reduction medical fluid is attached to 31 inner wall of tapered portion in mode Structural strength.
Further, the snap-in structure be set to 32 outer wall of pedestal two layers of annular rim 35 and with body 1 The annular recess 15 of outlet inside wall pairing setting reduces a possibility that drip nozzle 3 is prominent because of compressional deformation when body 1 is pressurized.
As another effective embodiment, it is additionally provided with bottle cap 2, sealing knot is provided on the inside of 2 upper wall of bottle cap Structure, as shown in Figure 1, enclosuring structure is cyclic annular flanging 22 and sealing salient point 21, in the case where bottle cap 2 covers tightly state, cyclic annular flanging 22 is supported The outer edge of tapered portion 31 is pressed, sealing salient point 21 compresses the outlet of taper flared aperture 33, separates the external world with space in bottle, avoid Medical fluid communicates with the outside world, and reduces contaminated possibility.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should It is subject to the protection scope in claims.
